Realistic Battery Operated Stereo Preamp

Battery Operated Solid-State Stereo Phono Pre-Amplifier

Realistic Battery Operated Stereo Preamp

Description

This stereo pre-amplifier is designed so you can use a magnetic phono cartridge (low level) with an amplifier/receiver/console which only has high level inputs such as crystal or ceramic phono, line or AUX inputs.

Typically a magnetic cartridge provides better sound quality and is less wearing on good records.

The pre-amplifier is housed in a sturdy but compact metal case the size of a package of cigarettes and operated from a single rectangular 9-volt transistor radio type battery.
